you can do:
var buffer: Array of byte;
SetLength(Buffer, 1000);
SerRead(Handle, Buffer[0], 1000);
I checked this out. It works not reliable. Sometimes I get real data,
sometimes the data are corrupted. I have no idea to rule out
corrupted data.
You have to check the result of the serread routine. Since it returns
the result of the fpread call, "man 2 read" will tell you what those
results mean. In short,
a) result >= 0: actual number of bytes read (the 1000 you pass is just
a maximum)
b) result < 0: an error occurred
Thank you. I checked this out, but every incoming character is
interpreted as zero, regardless of its real value.
